If I were you, I would tone down the "Filter>Render>Clouds". I understand they're useful in creating texture, but anyone who is familiar with Photoshop or similar fractal effects will find those distracting. A good rule of thumb when using generated filters is to them as subtly as possible. They're also compositionally confusing since they are of the same value as parts of your landmasses and there is such a large empty space on the right. If you put your image in grayscale, you'll see what I mean. Your focal point should clearly be the large landmass, but because the value of the clouds is similar to that of the land, the eye wanders. Just tone it down, crop the image, and things should be peachy keen.
